Sorry, it doesn't make much sense now I reread it.

I was meaning that you now have code that looks like:

int func()
#if something
  return 1;

  return 1;

where as before it was:

int func()
#if something
  return 1;
  return 1;

Personally I prefer the first version (as I know that there will always
be a return processed just by looking at the last line of the function)
but like I say the second layout was how it was in the past and should
avoid any compiler warning about "unreachable code" - could be that I've
made up that last warning - could have just been in an IDE :)

This point is mostly nitpicking tho', so probably best to ignore it :)

Cool. I'll pull it soon if Lennart doesn't beat me to it (seeing as he's
back soon) Probably tomorrow when I can do a few build tests etc. just
in case :)

Sorry for the delayed reply - mailing list borked :s
